iatented Mai". '19243 The present invention relates to such handgrenades as areiprovided with asafety device cornprising a throwsafetylever for holding the striker ofthe hand grenade cocked against itsspring, and a, ght'safety memberlfor holding the throw safety-lever'insafety position.

vThe chiefobject of the invention is to provide a hand grenade of' thistype, in which the fight safety member'isoperable by the throwing hand.

Further ebjects `of th 'invention win be apparent froniV thefollowingdescription of an embodimentfthereofiHustrated by wayof example in theaccompanying drawings Vin which:

Fig. 1 is a longitudinalfsfection of the hand grenade -iri vsafetypositiomthe section being substantially onthe line`I-I in Fig. 2.

Figs. 2- and 3V aresideand top views, respectively, of the head of thehandgrenade with the safety device in'safe'ty position.`

4 is ay longitudinal `section of the hand grenade with thefght and throwsafety device in the positionfoccupied at the moment when the handgrenade has just left the throwing hand'of the thrower. i

Fig. 5 is a plan view of a somewhat modied embodiment of the throw andiight safetydevice.

In the drawings, I indicates the cylinder-or body ofthe hand grenadeadapted to be filled with explosive. YIn the upper part of the grenadebody there is provided an opening 2, in which there is inserted a metaltube 3 the upper edge of which is bent about a flange 4 provided aroundthe opening 2 of the grenade body. That part ofthe tube which iissituated in the opening 2 is provided with tapped threads 5 for ascrewthreaded holder 6 containing the. igniter set of the handgrenade. Yl

The holder 6 is in the form of la tube which outsidev the 4grenade bodyI has a flange 1 which,

after the tubehas been screwed home, pressesV against a packing 8provided on 'top of the ange 4 of the grenade body I, thereby preventingdirt, moisture andthe like from penetrating into the interior of thegrenade body.

L In the tubular holder Slis mounted the `striker 9 and its spring I0,'one end ofwhich bears on a flange I Iprovided on the upper part ofthe holder, and the other end of which bears on a flange I 2 provided atthe lower end of the striker. Whenreleased the striker strikes apercussion cap or the like (notshownkwhich is placed at` the` top 0fanipp1e lascrewed into the 1pwer`end or :use insertedaltubeffl-sri.screwed into the nipfsrATEs PATENT jj `'ApplicationJanuary 21, 1946, seria1No.642,51s i' u `f j 'f In Sweden July 3, 1944 Yv uf.

ple I3 and leading to a detonator On either side of the projecting outerpart`V of the striker 9, there is provided on top of; the

'-iiange1 a substantially semi-circular lug I5`and,

safety position'this lever has. one arm 2I e111`I gaging in a transverserecess 23 in the projecte ing outer .part `of the striker 9. and theother arm 22 is lying against, or almost against, thegrenade body I,asshown in Fig. l. r, f' j When the thrower is about to throw the handgrenade, he shall grip the lever arm 22`and hold it securely against thegrenade body I against the action of the spring IIJ. At the moment when1 the throw has just been carried out and the 'grenade 'has thus leftthe throwing Vhand'of the thrower, the lever 2I, 22 will swing to theposition shown in Fig. 4 in which the lever is released from itsengagement with the recessed projectingA part of the striker 9, whichthus is released and strikes the percussion cap (not shown) on the g topof the nipple I3. Y

All the parts described above are previously known and thus do not formpart of the invention but only ofthe setting thereof. They mayV bevaried in'several different manners. The Vinventi'on consists in thefirst place inthe provision of .a fight safety member operable by thethrowing hand .and in the second place in the combi-y nation of saidiight safety member with a carriage safety pin.

-In the embodiments shown by way of example in the drawings the saidiight safety member, as best shown in Figs. 3 and 5, consists of ametalA wire bent to form a rectangular loop provided 4with a spring eye24. The free ends 25, 26 ofV the loop whenplacing it onto the head ofthe1` grenade for bringing it into its safety position,

the flange 1 of the holder 6 should project some what beyond theoutsides of the lugs I5 and I6,

as shown in1Figs.2and-f3. For the purpose of preventing the free endsof:

,fthe loop from sliding upwardly from `the safety4 rit adapted to 'causethe blasting charge to explode.

tangular loop at the end thereof engaged with the throw safety lever.

3. A hand grenade of the character described, comprising, incombination, a grenade body having an opening, a head screwed into saidopening and having, on top of it, two spaced approximately semi-circularprojecting lugs, said lugs having double inclined surfaces thereonconverging to a high point intermediate the top and bottom of said lugs,a spring-pressed striker mounted in said head and having a notched endprojecting into the spaces between saidlugs, a throw safety leverpivoted on said lugs and, when in its safety position, having one endengaged with the notched end of the striker to hold the latter in cockedposition against its spring and a iight safety member in the form of aresiliently expansible, .approximately rectangular wire loop swingablysecured at one end thereof to said throw safety lever and which, when inits safety position, embraces the projecting lugs on the head of thegrenade and holds the throw safety lever in its safety position, theother end of said ght safety member being closed and adapted to abut thesaid head at the side opposite from said throw safety lever, said loopbeing swingable about said throw safety lever out of its safety positionby the thumb of the throwing hand.

4. A hand grenade as claimed in claim 3, in which a. withdrawablecarriage safety pin penetrating the lugs and the projecting end of thestriker is disposed immediately above the side branches of theapproximately rectangular loop, 'when this is in its safety position, tolock the loop in this position.
